Comparison of Three Surgical Approaches for Lateral Sinus Floor Elevation
Sponsor: Istanbul Aydın University
Summary
This study compares three surgical approaches used during lateral sinus floor elevation, a procedure performed to increase bone height in the back part of the upper jaw before or together with dental implant placement. Participants are randomly assigned to one of three groups: a standard surgical procedure, a technique using an epinephrine-soaked cotton roll to help control bleeding, or a piezoelectric surgical technique. The study compares these approaches in terms of bleeding during surgery, visibility of the surgical field, ease of performing the procedure, operation time, and Schneiderian membrane perforation, an intraoperative complication that can occur during sinus lift surgery. Patient-related and anatomical factors, including age, sex, smoking status, residual bone height, sinus membrane thickness, lateral sinus wall thickness, and the presence of sinus septa, are also recorded. The aim is to determine whether the surgical approach influences intraoperative conditions and membrane perforation and whether patient-related or anatomical factors are associated with these outcomes.

Interventions
Conventional Rotary Lateral Sinus Floor Elevation
A lateral sinus window is created using a rotary round diamond bur. After removal of the bony window, the Schneiderian membrane is elevated using conventional manual sinus instruments. Membrane integrity is evaluated by direct visualization and the Valsalva maneuver. Subsequent grafting and implant-related procedures are performed according to the standardized study protocol.
Epinephrine-Soaked Cotton Roll
A lateral sinus window is created using a rotary round diamond bur. Following completion of the lateral sinus wall osteotomy, a cottonoid saturated with an additional 1 mL of Ultracain D-S Forte, containing 40 mg articaine hydrochloride and 0.012 mg epinephrine, is applied to the surgical field for 5 minutes to promote local hemostasis. After removal of the cottonoid, Schneiderian membrane elevation is continued using conventional manual sinus instruments. Subsequent procedures follow the standardized study protocol.
Piezoelectric Sinus Lift
The lateral sinus window is created using US2 and UL4 piezoelectric surgical tips. The Schneiderian membrane is subsequently elevated using UL2 and UL5 piezoelectric inserts, supplemented with conventional manual sinus instruments when necessary. Membrane integrity is evaluated by direct visualization and the Valsalva maneuver. Subsequent grafting and implant-related procedures are performed according to the standardized study protocol.
